Audio research VSi75 -why so many for sale?

This question is asked frequently about different equipment. Usually there is no specific reason for a large number of a particular item to be on sale.

There are some reasons that will cause a number of an item to go on sale such as a new model of a particular item coming out and fans want to upgrade, or a new item will come out with a lot of hype and people who try it aren’t impressed. It could still be a good product, but just doesn’t live up to the hype. You can get a good deal for either of these reasons if you know that you like the item. Don’t get fooled by hype yourself, though.

Most of the time it’s just coincidence.

An excellent amp. Reviews  give it high marks.  I have the vsi-60 and paired with the right cables, components and speakers it becomes a magical experience. At the current prices I would get one, but  at the moment  money is tight. 

It's probably a fluke that several VSi75's are available right now.   They are usually hard to find.   I'd like one to replace my VSi60 but I do balk a little.  The VSi75 is only available in silver and all of my electronics are black.
